 10代の父親からの子どもは健康状態に問題が多いとカナダからの報告。
 母親の年齢は出産時の問題と関連するが、なぜ若い父親が影響するのだろうか? 10代の父親は裕福ではなく、母親への感情面でのサポートが不充分のためではないかという。
 20代の母親から生まれた乳児について、父親の年齢と子どもの異常のリスクを調べると、20才以上の父親では特に異常のリスクはなかったが、10代では低出生体重が13%増加し、早産が15%増加しており、1年以内の死亡率が41%高かった。
 この結果が生物学的に持つ影響は大きなものがあり、より詳細な調査が必要である。

Child dads 'birth problems link'
http://news.bbc.co.uk/2/hi/health/7230240.stm
画像Babies fathered by teenagers are more likely to be unhealthy at birth, a study suggests.
The age of the mother has been linked to birth problems, but the Canadian researchers do not know why a younger dad might have an impact.
Specialists from the UK said that teenage fathers were generally less affluent, and might offer less emotional support to their partner.
The study, of 2.6 million mothers, features in Human Reproduction.

The magnitude of the risks to society could be huge, given the number of births worldwide, if the increases we found are truly attributable to paternal age
Professor Shi Wu Wen
University of Ottawa

All the women were aged between 20 and 29 when they gave birth, and the fathers divided into age groups, so that the babies of teenage dads could be compared with those fathered by older men.
Men aged 20 and upwards did not show any abnormal risk of fathering a child with birth problems.
However, the teenagers had a 13% increased chance of a low birthweight baby, a 17% chance of a small baby and a 15% increased chance of having a baby born prematurely.
The chances of a baby dying within the first year also increased by 41%.
Biological debate
Professor Shi Wu Wen, from the University of Ottawa who led the study, said the findings "warranted further investigation".
"The magnitude of the risks to society could be huge, given the number of births worldwide, if the increases we found are truly attributable to paternal age."
He could not rule out a biological difference in younger men which might be contributing, but said there were more obvious societal reasons.

A far more convincing explanation for the finding in this study is that older men are simply better able to provide for their pregnant partners than younger fathers
Dr Allan Pacey
British Fertility Society

"Young fathers are more likely to come from economically disadvantages families and to have lower educational attainment," he said.
"People from less affluent backgrounds are less likely to utilise prenatal care services."
Dr Susan Bewley, a consultant obstetrician and researcher at Kings College London, said social factors were more likely to be the reason.
"The question is how good a father can you be when you are a very young person? It's far harder to be a good provider when you are that age.
"It's also possible that a younger father will not offer the same kind of emotional support to a mother."
Dr Allan Pacey, Senior Lecturer in Andrology at the University of Sheffield and Secretary of the British Fertility Society, said that anything suggesting that younger men's sperm was causing the problem "bucked the trend" of many other studies.
"A far more convincing explanation for the finding in this study is that older men are simply better able to provide for their pregnant partners than younger fathers.
"It makes sense that babies born to older fathers probably have a better start to life."

若ければいいというものでもないのか・・・難しいなあ。
10代の父親を持つ新生児は早産や低出生体重のリスクが高い、カナダ研究報告(AFP BB NEWS)という記事を見つけた。カナダ・オタワ大学の研究チームの報告についてである。このチームは、10代の父親をもつ新生児と40代の父親を持つ新生児を比べてみた(女性は20〜29歳)。すると、調査の結果、10代の父親を持つ新生児は早産の割合が15%、低出生体重の割合が13%、生後4週間以内に死亡する割合が22%高いことが分かった。さらに生後4週から1年の間の死亡率は41%に上った。 ...続きを見る
